Other information should be available upon operator request. All components in any one fire sub-division, from fire or flooding for cables, see also 3. Annual survey should be carried out within three months before or after each anniversary msx of the initial survey. The DP-control system should prevent failures being transferred from one system to another.

Permanente link 5 Surveys, testing and the Flag State Verification 5. For each equipment class the associated worst case failure should be defined as in 2. Permanente link Preamble These Guidelines for vessels with dynamic positioning systems have been developed to provide an international standard for dynamic positioning systems on all types of new vessel. Where this is unavoidable such cables could run together in cable ducts of A class, the termination of the ducts included, which are effectively protected from all fire hazards, except that represented by the cables themselves.

The DP-control station should display information from the power system, thruster system, and DP-control system to ensure that these systems are functioning correctly. Cable connection boxes are not allowed in such ducts.

Example of tests and procedures after modifications and non-conformities see 5.

It is important that it is possible. Initial survey which should include a complete survey of the DP-system to ensure 654 compliance with the applicable parts of the guidelines. After such a survey, necessary tests should be carried out to demonstrate full compliance with the applicable provisions of the Guidelines. Member Governments are invited to bring the Guidelines to the attention of all bodies concerned, and apply the Guidelines to new vessels with dynamic positioning systems constructed on or after 1 Julyin conjunction with implementation of the provisions of paragraph 4.

The switch-over of control to the back-up system should cirv manual, situated on the back-up computer and io not be affected by failure of the main DP-control system.

For equipment class 3, one of each type of sensors should be connected directly to the back-up control system and separated by A. The software should be produced in accordance with firc appropriate international quality standard recognized by the Administration. Geldig vandaag Dit onderwerp bevat de volgende rubrieken. To achieve this philosophy the requirements have been grouped into three equipment classes.

Items listed above for class 2, and any normally static component is assumed to fail. Periodical survey at intervals not exceeding five years to ensure full compliance with the applicable parts of the guidelines.

Non-redundant connections between otherwise redundant and separated systems may be accepted provided that it is documented to give clear safety advantages, and that their reliability can be demonstrated and documented to the satisfaction of the Administration. Permanente link 1 General 1. The consequence analysis should provide an alarm if the occurrence of a worst case failure would lead to a loss of position due to insufficient thrust for the prevailing environmental conditions.

Position reference systems should be selected with due consideration to operational requirements, both with regard to restrictions caused by the manner of deployment and expected performance in working situation. If the language used is neither English nor French, the text should include a translation into one of these languages.

It should be possible to control the thrusters manually, by individual joysticks and by a common joystick, in the event of failure of the DP-control system. The thruster system includes: Else, the Administration or coastal State may decide the equipment class for the particular operation.

Bus-tie breakers should be open during equipment class 3 operations unless equivalent integrity of power operation can be accepted according to 3.

Any normally static component cables, pipes, manual valves, etc. The power system includes: The type of tests carried out and results should be recorded and kept on board.

For equipment classes 2 and 3, the DP-control system should include a software function, normally known as ‘consequence analysis’, which continuously verifies that the vessel will remain in position even if the worst case failure occurs. The transfer to redundant component or system should be automatic as far as possible, and operator intervention should be kept to a minimum. For equipment class 3, a single failure includes: Normally static components will not be considered to fail where adequate protection from damage is demonstrated, and reliability is to the satisfaction of the Administration.

Any such vessels should, however, comply with safety requirements which, in the opinion of the Administration, are adequate for the service intended and are such as to ensure the overall safety of the vessel.

For equipment class 3, at least one of the position reference cigc should be connected directly to the back-up control system and separated by A. The equipment class of the vessel required for a particular operation should be agreed between the owner of the vessel and the customer based on a risk analysis of the consequence of a loss of position.

The Administration may, however, entrust the surveys and testing either to surveyors nominated for the purpose or to organizations recognized by it.

Redundant computer cir should be arranged with automatic transfer of control after a detected failure in one of the computer systems. An uninterruptible power supply UPS should be provided for each DP-computer system to clrc that any power failure will not affect more than one computer.
